3. The method according to claim 2, wherein the second target sequence is used to indicate third information of the first sending device, and the third information comprises at least one of the following information: a synchronization source of the first sending device, a mode of the first sending device, a mode expected to be used by the first sending device, and a priority of the first sending device.
This invention relates to wireless communication systems, specifically methods for transmitting and receiving synchronization signals and related information in a decentralized network. The problem addressed is the need for efficient and reliable transmission of synchronization and operational status information between devices in a network where centralized control is absent or limited. The method involves a first sending device transmitting a first target sequence to a receiving device. The first target sequence is used to indicate first information, such as synchronization timing or channel state information. Additionally, the sending device transmits a second target sequence, which conveys third information about the sending device itself. This third information includes at least one of the following: the synchronization source of the device, its current operational mode, the mode it expects to use, or its priority level in the network. The second target sequence may be transmitted in a manner that allows the receiving device to distinguish it from the first target sequence, ensuring proper decoding and interpretation of the conveyed information. This approach enables devices to dynamically share critical operational details without requiring explicit signaling, improving network coordination and efficiency in decentralized environments.
6. The method according to claim 5, wherein the target code is a first codeword corresponding to the third mode.
A method for encoding data involves selecting a target codeword from a set of available codewords based on a specified mode. The encoding process includes determining a mode from multiple possible modes, such as a first, second, or third mode, where each mode corresponds to a different set of codewords. The method then selects a target codeword from the set associated with the determined mode. Specifically, when the third mode is selected, the target codeword is a first codeword from the set corresponding to that mode. The encoding method may also involve generating a codeword index based on the target codeword and transmitting or storing the encoded data. This approach allows for flexible encoding by dynamically choosing codewords based on the selected mode, optimizing data representation for different use cases. The method ensures efficient encoding by mapping the target codeword to a specific position within the codeword set, facilitating accurate decoding. The system may include a processor configured to perform these encoding steps, ensuring compatibility with various data transmission and storage applications.
8. The method according to claim 1, wherein the first target resource is used to indicate third information of the first sending device, and the third information comprises at least one of the following information; a synchronization source of the first sending device, a mode of the first sending device, a mode expected to be used by the first sending device, and a priority of the first sending device.
This invention relates to wireless communication systems, specifically methods for managing synchronization and resource allocation in networks where devices dynamically share information about their operational states. The problem addressed is the need for efficient coordination among devices to maintain synchronization, optimize resource usage, and prioritize communication based on device modes and roles. The method involves a first sending device transmitting a first target resource that conveys third information about the device. This third information includes at least one of the following: the synchronization source of the device, its current operational mode, the mode it expects to use, or its priority level. The synchronization source identifies the reference device or network element the sending device relies on for timing synchronization. The mode indicates the device's current operational state, such as active, idle, or low-power mode. The expected mode signals the device's anticipated state, allowing other devices to preemptively adjust their behavior. The priority level indicates the device's importance in the network, enabling prioritized resource allocation. By encoding this information in the first target resource, the method enables other devices to dynamically adapt their synchronization, resource allocation, and communication strategies based on the sending device's state and role. This improves network efficiency, reduces conflicts, and ensures reliable synchronization in dynamic wireless environments. The approach is particularly useful in decentralized networks where devices must autonomously coordinate without centralized control.
15. The receiving device according to claim 14, wherein the target code is a first codeword corresponding to the third mode.
A receiving device is configured to process signals in a communication system where data is transmitted using different modulation modes. The device includes a demodulator that receives a signal and extracts a target codeword from the signal. The target codeword corresponds to a specific modulation mode, such as a third mode, which may involve higher-order modulation schemes like 16-QAM or 64-QAM. The device also includes a decoder that decodes the target codeword to retrieve the transmitted data. The demodulator may further determine the modulation mode used for the signal by analyzing a preamble or a pilot signal, ensuring accurate demodulation. The device may also include error correction mechanisms to handle signal distortions or interference. The receiving device is designed to efficiently switch between different modulation modes, optimizing data throughput and reliability in varying channel conditions. This approach enhances communication efficiency by dynamically adapting to the signal characteristics and transmission requirements.
17. The receiving device according to claim 10, wherein a first resource of one first mode or one first synchronization source comprises at least one of the following resources used to transmit corresponding first target information: a resource pool, a carrier, a bandwidth part BWP, a time domain resource, and a frequency domain resource.
This invention relates to wireless communication systems, specifically improving resource management for transmitting target information in different modes or synchronization sources. The problem addressed is the efficient allocation and utilization of communication resources to ensure reliable transmission of critical data, such as synchronization signals or control information, across varying network conditions. The invention describes a receiving device configured to handle a first resource associated with a first mode or synchronization source. This resource can include one or more of the following: a resource pool, a carrier, a bandwidth part (BWP), a time domain resource, or a frequency domain resource. These resources are used to transmit corresponding first target information, which may include synchronization signals, control channels, or other essential data. The receiving device is designed to dynamically select and manage these resources to optimize transmission efficiency and reliability. The first mode or synchronization source may refer to different operational states or synchronization mechanisms within the wireless network, such as initial access, handover, or device-to-device (D2D) communication. The resource pool defines a set of available resources for transmission, while the carrier and BWP specify the frequency bands and sub-bands used. Time and frequency domain resources further refine the allocation within these bands. By leveraging these resources, the receiving device ensures that the first target information is transmitted accurately and efficiently, adapting to the network's dynamic requirements. This approach enhances overall system performance and reliability in wireless communication environments.
